Journal of Nutritional & Environmental Medicine (2002) 12(3), 187–196A Multi-country Ecological Study of Dietary Risk andRisk-reduction Factors for Prostate CancerWILLIAM B. GRANT PHD12 Sir Francis Wyatt Place, Newport News, VA 23606–3660, USAWBGrant@infi.netAbstractPurpose: To investigate dietary factors for prostate cancer mortality (PrCM).Design: An ecological analysis was performed using age-strati ed multi-country PrCMrates and dietary supply data.Materials and Methods: The PrCM rate data were obtained from the World HealthOrganization. The dietary supply data were obtained from the Food and AgricultureOrganization of the United Nations. Multivariate regression analyses were performed withgroupings of countries based on geopolitical associations. A time lag between diet andmortality of up to 19 years was used.Results: The consumption of vegetable protein was found to be an important risk-reductionfactor for PrCM as one factor in a multivariate regression analysis. In addition, a highconsumption of vegetable products as a fraction of total energy was inversely correlatedwith PrCM. In contrast, a high consumption of animal products as a fraction of totalenergy, animal fat, the non-fat portion of milk, and added sugar, was found to be a riskfactor for PrCM.Conclusions: This study supports previous ndings for milk and calcium, animal fat,animal products, vegetables and vegetable products, and extends the literature with thending that added sugar is an important risk factor. The high inverse correlation betweenPrCM and the consumption of vegetable protein is probably due to the high iso avonoidsand lignan content in foods such as pulses (beans) and whole grains. Animal products,which induce the expression of insulin-like growth factor-1, and dietary sweeteners, whichalso increase insulin production, may enhance prostate cancer development and subsequentmortality. It is hoped that these results will be tested in case-control and cohort studies.Keywords: animal products , calcium, diet, IGF-1, insulJournal of Nutritional & Environmental Medicine (2002) 12(3), 145–151Is Milk Best for Infants and Toddlers?R.
